How this works. Every geocoded 311 noise complaint in San Francisco from May 2025 through May 16, 2026 is weighted by time-of-day (2× for 10pm–7am) and complaint type, then smoothed into a 200m grid via Gaussian KDE. The colour shows relative complaint density — redder blocks received more complaints, greener blocks fewer. Tap any block or search an address to see the raw complaint count nearby. Full methodology.
